A trial of structured debate as a self-learning method for students and young healthcare providers to discuss social issues in general and family medicine: A case report in Japan.

The structured debate as a means of medical education for medical students and young healthcare providers was performed, with diverse topics related to general and family medicine.

Addressing Vaccine Hesitancy and misinformation amidst Japan's self-amplifying mRNA COVID-19 Vaccine Rollout.

As of October 1, 2024, Japan implemented a revised COVID-19 vaccination strategy, shifting from a fully publicly funded model to one where costs are partially or fully borne by recipients. This new annual program targets individuals aged 65 and above, and those aged 60-64 at higher risk of severe illness, requiring them to cover some vaccination expenses. For others, the vaccine remains voluntary and self-funded.

Continued cancer drug approvals in Japan and Europe after market withdrawal in the United States: A comparative study of accelerated approvals.

Regulatory authorities must balance ensuring evidence of efficacy and safety of new drugs. Various regulatory pathways, such as the accelerated approval program in the United States (US), allow authorities to quickly approve drugs for severely ill patients by granting market authorization based on surrogate end points and pending confirmatory trials. In this cross-sectional study, we considered 23 indications of cancer drugs that received accelerated approval by the US Food and Drug Administration (FDA) but were subsequently withdrawn as of April 2023.

Illicit Trade of Prescription Medications Through X (Formerly Twitter) in Japan: Cross-Sectional Study.

Background: Nonmedical use of prescription drugs can cause overdose; this represents a serious public health crisis globally. In this digital era, social networking services serve as viable platforms for illegal acquisition of excessive amounts of medications, including prescription medications. In Japan, such illegal drug transactions have been conducted through popular flea market applications, social media, and auction websites, with most of the trades being over-the-counter (OTC) medications.

The "Okusuri Charm" movement in Japan: Prescription drug accessories emerging on X (Twitter).

Background: In this digital age, social networks may offer an avenue for individuals to obtain drugs illicitly beyond the prescribed amount. Users on X (Twitter)® have ingeniously fabricated fashionable accessories that employ prescription drug sheets, termed "Okusuri Charm".

Methods: This cross-sectional study scrutinized the emerging "Okusuri Charm" trend, by searching the term in Japanese on X (Twitter)® and analyzing related posts.

RNA-based cooperative protein labeling that permits direct monitoring of the intracellular concentration change of an endogenous protein.

Imaging the dynamics of proteins in living cells is a powerful means for understanding cellular functions at a deeper level. Here, we report a versatile method for spatiotemporal imaging of specific endogenous proteins in living mammalian cells. The method employs a bifunctional aptamer capable of selective protein recognition and fluorescent probe-binding, which is induced only when the aptamer specifically binds to its target protein.

Non-genetic cell-surface modification with a self-assembling molecular glue.

This report describes the development of a non-genetic cell-surface modification method, in which a self-assembling small molecule is combined with Halo-tag proteins. Cell-surface functionalization with cancer-linked extracellular proteins led to enhanced cell motility, angiogenesis, and immune shielding of the cells, paving the way for translational opportunities for cell therapy.

A prospective compound screening contest identified broader inhibitors for Sirtuin 1.

Potential inhibitors of a target biomolecule, NAD-dependent deacetylase Sirtuin 1, were identified by a contest-based approach, in which participants were asked to propose a prioritized list of 400 compounds from a designated compound library containing 2.5 million compounds using in silico methods and scoring. Our aim was to identify target enzyme inhibitors and to benchmark computer-aided drug discovery methods under the same experimental conditions.

Multifunctionalization of Cells with a Self-Assembling Molecule to Enhance Cell Engraftment.

Cell-based therapy is a promising approach to restoring lost functions to compromised organs. However, the issue of inefficient cell engraftment remains to be resolved. Herein, we take a chemical approach to facilitate cell engraftment by using self-assembling molecules which modify two cellular traits: cell survival and invasiveness.

Fabrication of a Multiplexed Artificial Cellular MicroEnvironment Array.

Cellular microenvironments consist of a variety of cues, such as growth factors, extracellular matrices, and intercellular interactions. These cues are well orchestrated and are crucial in regulating cell functions in a living system. Although a number of researchers have attempted to investigate the correlation between environmental factors and desired cellular functions, much remains unknown.
